WVILLIAM l3. RUSH, OF DECATUR, ILLINOIS, ASSIGNOR TO CHAMBERS,

BERIN G QUINLAN COMPANY, OF SAME PLACE.

CORN -PLANTER CHECK-ROWER.

sPnoIrIcArroN forming part of Letters Patent No. 298,895, dated May 20,1884.

Application filed October 5, 1883. (No model.)

T0 on whom it may concern:

Be it known that I, WVILLIAM B. RUSH, a citizen of the United States,residing at Decatur, in the county of Maconand State of Illinois, haveinvented certain new and useful Improvements in Oorn-PlanterChecloltowers and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanyand to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 is a top plan of a check-rower embodying my invention. Fig. 2is an enlarged top plan of portions of the device. Fig. 3 is a top planof same parts shown at Fig. 2, but in different relative positions fromthat shown at said figure. Fig. 4 is a top plan of the auxiliary leverG. Fig. 5 is a perspective of the bars or levers A and G.

My invention relates to that class of checkrow attachments tocorn-planters a type of which is shown at Fig. 1, in which a rocking oroscillating bar, A, is connected by suitable means with and transmitsmotion to the seedslides, and receives motion from bars B B on one sideof the bar A, as shown in Patent No. 251, 830, or on both sides thereof,as shown in Patent No. 258,216, and in which the bars B B receive motionfrom a push-bar, O, which is actuated by connection with forked levers Dand a stretched tappet-wire, E.

My improvement consists in the use of an auxiliary rocking bar or lever,G, arranged intermediate or between the bar A and the link F, or otherdevice for transmitting motion to the seed-slides, and adapted not onlyto transmit motion from the bar A to the link F, but to act also as astop to prevent the momentum of the parts carrying the bar A too farwhen it is swung, and as a lock to prevent any rebound of the bar A orseed-slides, as hereinafter described.

The bar Gis pivoted near its mid-length to the frame-bar H, or a lug, h,projecting laterally from said frame-bar, and has holes fin its outerend, which receive a bolt or pin, f, to connect the link F therewith.The inner end of the bar G is forked or terminated by two limbs or ends,9 g, with a semicircular groove, 9, between them. The under side of oneend of the bar A is cut away to form alaterally-projecting shoulder, a,on each side of the bar A, and the bar G is located with its forked endbeneath this cut-away portion of the bar A, and in such position withreference to the shoulders a that rocking the bar A on its vertical axisa will bring the shoulders a alternately in contact with the concaveconfronting sides of the limbs g g, and thereby give an oscillatingmotion to the seed-slides through the connecting-rod F or otherintermediate mechanism. The bar A has also a laterally-projectingshoulder, a, oneach side of its axis of oscillation. When the bar A isgiven a throw in one direction by impact of the forked lever with atappet on the tappetwire, (see Fig. 1,) the limb g is brought thereby incontact with one of the shoulders a and arrests the movement of the barA, and thus prevents the momentum of the parts carrying it or otherparts out of proper positions, and at the same instant the limb g isbrought in contact with a shoulder a, and prevents any movement backwardof the bar A from rebounding of it or the seed-slides. Vhen the bar A'isgiven a throw in the opposite direction to that last described, as shownat Fig. 2, the'limb y then acts on a shoulder a, to arrest the movement,and the limb g 011 a shoulder a, to prevent rebound.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a check-row attachment to corn-planters, in combination with theoscillating lever A, having shoulders a a, the auxiliary lever G, havinglimbs g 9, adapted to receive motion alternately from the shoulders a,and to act alternately 011 the shoulders a as stops, and to transmitmotion through suitable mechanism to the planter seed-slides,substantially as and for the purpose specified.

2. I11 combination with the rocking lever A, which receives motionindirectly from the forked levers D, and has lateral shoulders at, thelever G, arranged between the lever A and mechanism connected with theplanter seedslides, and provided with limbs g 9, adapted to receivemotion from the lever A, and to act alternately on the shoulders a asstops, substantially as and for the purpose specified.

3. In combination with the tappet-wire E, forked lever D, push-bars Oand B B, and rocking lever A, the auxiliary lever G, adapted to receivemotion from the lever A, and its arms 9 g, to act alternately on theshoulders at a as stops, substantially as and for the purpose specified.

4:. In combination with the forked lever D, push-bars O and B B, androcking lever A, having shoulders at a, the auxiliary lever G, havinglimbs g 9, adapted to coact with the shoulders a a, substantially as andfor the purpose specified.

5. In combination with the push-bars O and B B and rocking lever A, theauxiliary lever G, provided with stops, and adapted to receive motionfrom and to the motion of the lever A, and to impart movement to theplanter seed-slides, substantially as and for the purpose speoified.

In testimony whereof I affix my signature in presence of two witnesses.WILLIAM B. RUSH.
